What to do if the pain persists after a burn?
After a burn, the pain persists primarily because the wound was not properly treated. The most common and simplest method in the early stages of a burn is to soak the burn in cold water or rinse it under running water for over half an hour. This can help wash away the residual heat on the surface, especially making it more effective for acid or alkali burns. Alternatively, you can use an ice pack to cool the area. After cooling, apply some burn ointment. If the pain is severe, pain-relieving medication can be used to treat symptoms, such as ibuprofen. If the pain is unbearable, it is advised that the patient should go to the hospital for timely examination and symptomatic treatment.
Drug allergy symptoms
Drug allergies mainly manifest as skin itching, red rash, and papules; severe cases may experience ulceration, exfoliative dermatitis, in the respiratory system it may present as nasal congestion, breathing difficulties, and laryngeal edema; in the digestive system, patients may experience abdominal pain and diarrhea, sometimes accompanied by joint pain and swelling, immune dysfunction, and the occurrence of allergic purpura. Some drug allergies can cause neurological reactions, such as dizziness and headaches. When a drug allergy occurs, immediately stop using the suspected medication, and simultaneously take anti-allergy medications such as loratadine, cetirizine, or administer diphenhydramine via muscular injection. Oral intake of compound glycyrrhizin capsules may be considered. If there is laryngeal edema, it is crucial to seek prompt medical attention at a hospital, actively manage the allergy, and severe cases may require a tracheotomy for rescue. (Specific medication usage should be conducted under the guidance of a doctor, and medications should not be used without authorization.)
How long will it take for a burn with broken skin on the finger to heal?
When a finger is scalded, local symptoms such as swelling, redness, heat, and pain—an inflammatory response—will occur. The patient will experience significant pain and a burning sensation. Under these circumstances, it is essential to clean the wound promptly to prevent infection. If there is broken skin, it needs to be disinfected with hydrogen peroxide, then rinsed with saline solution, followed by an application of iodine. It is important to keep the skin at the broken site dry and avoid contact with water and contaminants. With such treatment, the broken skin typically forms a scab within about a week. After another week, the skin in the affected area will heal and regenerate.
Symptoms of alcohol allergy shock
Patients with an allergy to alcohol can experience allergic shock, exhibiting symptoms like chest tightness, palpitations, a sensation of throat blockage, breathing difficulties, and a flushed face. Additional symptoms include dry mouth, dizziness, blurred vision, numbness in the face and limbs, and circulatory system failure, indicated by chills, cold sweats, cyanosis, restlessness, a weak pulse, and even a drop in blood pressure. Some patients may also experience loss of consciousness, coma, convulsions, and incontinence. Due to the alcohol allergy, patients may show allergic reactions like skin itching, hives, or other rashes. A minority of patients may also have abdominal pain, diarrhea, nausea, vomiting, sneezing, and fever.
Alcohol allergy symptoms
If a patient is allergic to alcohol, the following symptoms may occur: the patient will feel itchy all over, their skin will turn red, and they may experience welts and rashes. Some patients may also experience chest tightness, shortness of breath, palpitations, dizziness, and even fainting, profuse sweating, and transient loss of consciousness. If a patient exhibits profuse sweating along with transient fainting and loss of consciousness, this indicates a severe condition that requires emergency medical treatment at a hospital. Anti-allergic measures should be taken to alleviate the allergy symptoms. Additionally, due to the allergy, the patient may experience a relative insufficiency in blood volume, necessitating fluid replenishment treatment. Therefore, patients with an alcohol allergy should avoid exposure to alcohol to prevent triggering allergic symptoms and endangering their lives. (Medications should be used under the guidance of a doctor.)
Alcohol allergy causes
Alcohol allergy, also known as ethanol allergy, occurs because normally, ethanol in the body is converted into acetaldehyde. People with alcohol allergies lack the enzyme needed to convert acetaldehyde, therefore cannot expel acetic acid from the body, resulting in acetaldehyde poisoning and various allergic symptoms. People who can consume large amounts of alcohol usually have a higher amount of this acetaldehyde converting enzyme, allowing them to quickly convert it without experiencing poisoning or allergic symptoms. Alcohol allergies are mostly linked to an allergic constitution; thus, individuals with this constitution will display various allergic symptoms upon exposure to alcohol, the allergen.
How to relieve skin allergy itching caused by formaldehyde poisoning?
The patient, due to formaldehyde poisoning, has developed skin allergies and itching. It is important to remember not to scratch the affected areas, to promptly leave the environment containing the allergen, and to avoid exposure to sunlight and ultraviolet lamps. If the patient's condition is mild, bathing in salt water can be effective in alleviating the itchiness caused by the allergies. If the itching is more pronounced, oral administration of antihistamines such as cetirizine and loratadine can be used to relieve the symptoms. If the condition is particularly severe, it may be necessary to go to the hospital for infusion therapy. During the infusion, medications that enhance the body's immune system and corticosteroids for symptomatic treatment may be administered. Additionally, during the allergic reaction phase, the patient should avoid using cosmetics and refrain from consuming potentially irritating foods like fish and shrimp, to prevent exacerbating the allergic reaction.
